large scale, of the spacing-escapement dogs. The platcns andpaper-feecZ.-The checkY 2 y @sasso (indicated by the shading on Figs. 1and 2) is placed on afiat platen 35 and its rear edge secured under theroll or bar 36, which clamps the check to the platen, said roll 36having iiattened ends, which can rise in the slots of the ears 37 of theplaten, Figs. 1 and 3, so that the edge of the check can be insertedunder said roll 36. Said platen 35, being preferably a thin flat plateof metal and widened at its rear end, as seen in Figs. 1 and 2, at eachside, is at those widened rear parts fixed to horizontal racks 40 40,with which mesh pinions 41 41, Vfixed on the cross-shaft 42, which turnsin said cover 2 and is at its outer end provided with a knurled head, asshown. Said racks 40 are fastened to the bent-down edges of the platen35, which edges move in parallel guides 45, which are formed on thesides of the cover 2. The construction is clearly indicated by dottedlines in Fig. 3, and the slots are seen in Fig. 1. Thus by turning theshaft 42 the platen can be moved toward the front or rear of themachine. Y

On shaft 42 is a loose roller 50, having a ratchet-wl1eel51 fixed on oneend, with which engages a pawl 52, which is carried on an arm 53, thatis fixed on said shaft 42, and the teeth of ratchet-wheel 51 are so cut'that when shaft 42 is turned to move platen 35 rearward roller 50 willbe revolved, but that shaft 42 may be turned in the opposite directionwithout revolving said roller 50. In frictional contact with said roller50 is roller 55, fixed on a shaft 56, which turns in the cover 2. Thepaper strip P for the duplicate record being originally wound on thespool 57 goes partly around roller 50 and between it and roller 55,partly around roller and up over the papercarrier or -round platen 58,and then to the spool 59, on which it is wound as the machine isoperated. The hub 60 of said spool 57 is provided with a friction-brake62, carried on the cover 2, the pressure of the brake being regulated bythe screw 63, Fig. 5. A ratchetwheel and pawl 66 permit spool 57 to turnfor unwinding strip P, but prevent its turning in the reverse directionuntil pawl 66 is thrown out of engagement with said ratchet-wheel 65,. Aratchet-wheel 193, with pawl 191, is

also provided for spool 59. Said ratchet-wheel 193 and pawl 191 permitthe spool 59 to turn in the direction of the arrow, Fig. 3, to wind npthe strip P on said spool 59, and thereby draw said strip P through themachine in the required direction, but they prevent the said spool 59from being accidentally or surreptitiously rotated in the reversedirection, and therefore the strip P cannot be drawn back so as todisclose a record that has been wound up on the said spool until theperson who has the key for unlocking the box opens said boil and by handdetaches said pawl 191 from said ratchet-wheel 193. A larger pulley onspool 57 and a smaller pulley on spool 59 are connected by belt 67, asshown. Thus when the movement of the platen 35 and its racks 40 revolveroller 50'in the manner 'hereinbefore with the said roller 50 by theroller 55, and

-the strip revolves the spool 57 in the direction of the arrow in Fig.3. The rotation of said spool 57 is communicated through its pulley tothe said belt 67, Fig. 5, and said belt 67 causes the spool 59 torevolve, so as to take up the strip Pas it is unwound from said spool57. The pulley of spool 59 is made smaller than that of spool 57, sothat the more rapid rotation of spool 59 shall compensate for the largerdiameter of the roll of paper on said spool 57 when the strip isbeginning to be wound on spool 59. As the paper unwinds from the spool57 and winds upon spool 59, and spool 59 tends to wind up the strip morerapidly than it comes from spool 57, belt 67 slips on one or both of thepulleys, being loose enough for the purpose, and the strip continues tobe wound without slack and without being torn.

The type-wheels andprntz'ng mechanism.- Two type-wheels-70 for theoriginal and 71 for the duplicate record-each containing the samecharacters similarly arranged, are fixed on the shaft 73, which turns inboxes 74 75 on standards or brackets 76 77, which are fixed on thecarriage 14. Both type-wheels have substantially the same construction,which is preferably the following: An inner annular plate is bolted toan outer flanged plate 81, and the ange 82 of the latter is providedwith radial slots 83 in number equal to the number of characters to beprinted. All said slots terminate at their inner endsin an annular spacearound the hub 85 of said plate 81. Thus when the plates 80 81 arebolted together there are formed chambers, each of which is adapted tocontain two type, r S, r being the lower and S the upper case letters,and the inner ends of said type project into the aforesaid annularspace, so that they can be struck by the hammers 91. Of course thechambers for figures, punctuation-marks, Jac., will contain only onetype. Each type is engaged by the end of a spring 92 or 93, whichvisfastened to the plates 80 or 81, the ends of the springs passing inthrough holes 94 95 intheir respective plates to engage the type, so asto hold the same normally inward-t'. e., out of the printing position.Said shaft 73 has a sliding fit in the boxes, and the bevel-gear 100,Figs. 1, 3, and 8, has a sliding fit on the square front end ofsaidshaft 73. Said gear 100 is held against lateral movement by thecollar 101, in which the hub 102 of said gear is centered, and the ring103 on said hub, and said collar 101 is carried by the stationary arm105, which is fixed on the upper end of the said fulcrumpost 106, whichis fixed inthe aforesaid spider 32 of the carriage 14. Said gear 100meshes with the horizontal bevel-gear segment 110, the hub 111 of whichfulcrums on said post IIO 106, Figs. 3 and 14. In the standard 112 ofsaid segment 110 is pivoted the printing-lever 115,y the slot 116 ofwhich spans with nice fit the neck of the anged collar 117, which workson said hub 111. The under side of said printing-lever 115 is providedwith bosses 119, which engage and depress the ange 118 of said collar117 when said leveris depressed, and said collar is normally elevated bythe spring 120. Said lever 115 is provided with a knife 122, whichenters the slot 31 corresponding to the -character which is to beprinted when the lever 115 is depressed. Said fiange 118 engages aroller 125 on an arm 126, which is fixed on the shaft 12,8, on which arealso fixed the aforesaid hammers 90 91. Thus the depression ofprinting-lever lldepresses arm 126, and that causes the said hammers 9091, which are curved, as seen in Fig. 2, to knock down and impress thattype which corresponds to the slot in which knife 122 has entered on thecheck and the duplicate strip. To facilitate accurate adjustment of saidhammers, screws 130 in arms 131 of said shaft 128 are provided, suitablesprings holding said hammers normally up from said arms 131. Saidhammers 90 91 are normally held up and out of engagement with the typeby the spring 135.

The types7mft-Fulcru med on a cross-shaft 140, Fig. 1, is an arm 141, onwhich is the capital shift-key 142. Fitted on the eccentric 143 of saidshaft 140 is one end of a rod 145, the other end of which connects withone end of a horizontal lever 146, which is pivoted at 147 in thestandard 76, and on its other end carries a fork which engages thecollar 148 on the type-wheel shaft 73. Thus by depressing key 142 shaft140 being rocked moves rod 145 and that lever 146, so as to shift theshaft 73 and type-wheels 90 91 to the rear and so as to bring thecapital letters S S under the hammers 90 91. A spring 149 normally holdsshaft 140 in suchposition that the lower-case letters r r are under saidhammers.

The rbhon-feed.-The ribbons 150 151 for the type-wheels 71, beingoriginally wound, respectively, on the spools 152 155, are led undertheir respective wheels and their ends attached in the usual manner tothe spools 154 153, spools 152 155 being both fixed on the shaft 157 andspools 154 153 being both fixed on the shaft 156. On said shafts 156 157are ratchet-wheels 160 161, respectively, with teeth suitably inclined.A pawl 163, pivoted in a slide 164, which moves trans- Versely on aguide 165, which is fixed on one of the boxes of shaft 73, Fig. 7, isadapted to engage one or the other ratchet-wheel 160 161, as desired,and said slide 164 is connected with a lever 168, pivoted at 170 andconnected by rod 171 with an arm 172 on said rock-shaft 128. Thus in theposition of Fig. 7 when the shaft 128 is rocked to print a character theslide 164 moves to the right and the pawl 163 passes by the teeth of theratchet-wheel 161 without moving it; but as the shaft 128 rocks back andthe hammers 90 91 rise the said pawl 163 rotates ratchet-wheel 161 withshaft 157 and spools 152 155 a little, so as to bring a fresh part ofthe ribbons below the wheels. When desired, the pawl 163 can be thrownover into engagement with the ratchet-wheel 160, and then the operationof shaft 128 will move that wheel160 with shaft 156 and spools 153 154so as to reverse the movement of the ribbons.

The spacing mechanism cmd escapemens-- The line-spacing movements of theplaten 35 are eected by the pinions 41 on the shaft 42, as will beevident from the description hereinbefore given, the movement of saidshaft 42 rotating the roller 50 and that feeding the strip P, so thatthe duplicate record will have proper line-spacing.

The letter and word spacing movements of the carriage 14 are effected asfollows: On shaft 128 is fixed an arm 175, which at its inner endengages an arm 176 of the escapement-dog 25, Figs. 2, 3 and 13, so thatwhen said shaft 128 is rocked to impress a character on the paper saiddog 25 passes into engagement with the rack 28 on the shaft 12 and holdssaid carriage 14 at rest, while the pivoted dog 26 passes out ofengagement with said rack. Then when shaft 128 returns to its originalposition dog 25 passes out of and dog 26 into engagement with said rack28 and the carriage moves one space in the ordinary manner. The springs178 V179 respectively hold said dogs 25 and 26 in their normalpositions. No further description of the escapement-dogs is necessary,as their construction and operation are well known in the art.

To enable the operator to space the carriage without printing, aspace-key 180, Figs. 1 and 2, is provided on a lever 181, pivoted at182. The rear end of lever 181 engages under the end of a cross-lever184, which is loosely fulcrumed on shaft 128, the inner end of saidlever 184 engaging on the aforesaid arm 176 of the escapement-dog 25. Asuitable spring 190, if necessary, normally holds space-key 180 up. Thedogs 25 and 26 are preferably carried on a piece 185, which is providedwith slots 186, by which it can bey accurately adjusted and screwed tothe carriage 14.

The machine is operated as follows: The parts being in the position ofFig. 3, but the platen 35 being in its front or original position, theoperator moves printing-lever 115 over that slot 31 which corresponds tothe characters he wishes to print, thereby setting the type-wheels 70 71for that character through the connection of the gear-segment 110 andgear 100. The operator then depresses said lever 115, engaging knife 122into the said slot 31, whereby the lever 115 is held in a true lateralposition. As it descends the ange 118 of collar 117 depresses arm 126and that rocks shaft 128, thereby causing the hammers 90 91 to knockdown the proper type and make the proper impressions simultaneously onthe check and the dupli- IIO cate strip, the type of wheel 71 passingdown through a slot which is formed in the cover 2 for the purpose. Asthe hammers and type rise the carriage 14 moves one space. When a line`is completed, the operator turns shaft 42, so as to move platen 35rearward the proper distance to cause the next line to be spaced theproper distance from the preceding line, and the rollerO moves theduplicate strip P a corresponding distance to cause the next line to beproperly spaced on the duplicate record. Then the operator, having drawncarriage 14 back to thebeginning of the line, writes another line on thecheck and duplicate, and so on. When securinga check on the platen, thecarriage 14 is turned up on shaft 12 and platen 35 drawn forward. Thenthe check is secured on the platen under roll 36, as hereinbeforedescribed, the carriage 14 lowered to writing position, and the checkwritten, as before. To make corrections or for any other purpose, thecarriage may also of course be turned up on shaft 12. belt 67 can slip alittle on its pulleys, so that no undue strain will be put on theduplicate strip P as the size of the roll of paper on the spool 59increases, and the arrangement of the belt and pulleys is such as tokeep the said strip taut.
